GPS Control IC for Samsung Galaxy S10 Plus

The GPS Control IC in your Samsung Galaxy S10 Plus receives the raw radio frequency signals from the GPS Antenna and processes them — decoding satellite timing data, calculating the device's precise geographic coordinates, and delivering accurate location information to the operating system and navigation apps. Without a functioning GPS Control IC, your Samsung Galaxy S10 Plus cannot determine its location regardless of antenna condition or software settings.

If the GPS Antenna is confirmed intact and correctly connected — verified by a technician — but the Samsung Galaxy S10 Plus still cannot detect any satellites or calculate a location, the GPS Control IC is the likely board-level cause. A technician can further confirm using RF diagnostic tools to check whether the antenna is receiving signals that the IC is failing to process.

GPS Control IC failure is less common than antenna or flex cable damage but occurs due to power surge damage, liquid ingress reaching the motherboard, or physical shock damaging the solder joints on your Samsung Galaxy S10 Plus. It becomes the diagnosis after ruling out all physical antenna components.

No. The GPS Control IC is a micro-SMD chip soldered onto the Samsung Galaxy S10 Plus motherboard. Replacement requires hot air rework equipment, flux, and advanced board-level repair skills. Attempting this without proper tools causes permanent motherboard damage.

Yes — a 7-day replacement warranty against manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Once the chip has been soldered it is considered used and cannot be returned. For more information, check out SAHII's Return Policy.
